I find that orchestral music is best for tuning the high and low end, and string quartets are good for the middle.
Once you get a reasonably flat response out of your headphones, just about anything that is calibrated flat will sound perfect. Most really good recordings are calibrated to flat response. Unfortunately, a lot of pop music is all over the map. It will take tone controls from album to album to pull those roughly into line.
Thanks again for your helpful information, bigshot!
I currently own Audio Technica ATH-ES7 which is pretty much old model for the AT headphones line. There are some reviews on the net say this one is good for acoustic pieces. I have tested with some mp3 piano pieces and I heard the sharp, clear sound came from the ES7. It might be just my own experience but I wonder if this headphones good enough to EQ acoustic music? Are there alternatives that sound much better?
P/S: I am currently tight with my budget so I prefer the affordable but good headphones.
